After an explosion occurs in an explosion-proof distribution box, emergency measures should be taken immediately: cut off power, isolate, and then use appropriate fire extinguishing equipment, and firefighting must be carried out in the correct sequence.。

What are the causes of explosion in explosion-proof distribution boxes?

1. The aging and over-lifespan use of wires and electrical components in explosion-proof distribution boxes: some explosion-proof electrical equipment in factory workshops was installed many years ago and has already aged. Combined with the large industrial power consumption and excessive load, short circuits at the wiring terminals inside the explosion-proof distribution box can easily occur, producing electric sparks. When these sparks come into contact with flammable and explosive gases that have entered the explosion-proof distribution box, an explosion can easily result. Additionally, explosion-proof distribution boxes also have a service life, though it is not fixed; it is determined based on the maintenance condition of the box. The typical service life ranges from 8 to 15 years.

2. In chemical plants and other factory areas, improper or non-compliant use of explosion-proof distribution boxes is also an important cause of explosions.。

3. Explosion-proof electrical equipment manufacturers cut corners, and counterfeit and inferior explosion-proof distribution boxes flood the market.。

Although national regulations explicitly prohibit manufacturers without production licenses and explosion-proof certificates from producing and selling explosion-proof electrical equipment products, some small factories still mass-produce inferior explosion-proof electrical equipment for profit, and distributors still sell them.。For example: explosion-proof distribution boxes and explosion-proof positive-pressure cabinets produced by legitimate manufacturers are sold at a price of 5,000 yuan. However, some distributors, for profit, purchase low-priced explosion-proof distribution boxes, explosion-proof small rooms, and other explosion-proof electrical equipment from unqualified small factories to gain greater profits, thereby harming the interests of end users. The explosion-proof distribution boxes purchased from small factories use simple materials and are not produced in accordance with the national explosion-proof standard 3836, posing huge safety hazards.。

Explosion-proof safety work is very important for enterprises in hazardous gas environments such as chemical plants.。Enterprise explosion-proof safety requires necessary training for electricians, eliminating unlicensed work, strictly prohibiting illegal operations, and adopting basic explosion-proof measures for explosion-proof electrical equipment, including correctly selecting explosion-proof electrical equipment, installing them reasonably in accordance with codes, and strengthening maintenance and upkeep.。Outdoors, rain protection measures should be considered for explosion-proof electrical equipment, good ventilation devices should be provided, fire-resistant facilities should be commonly used, and grounding must be carried out in accordance with regulations, etc.。
